OBJECTIVETo evaluate the efficacy and safety of the combination therapy of Xipayimaizipizi Capsules and Tamsulo- sin in the treatment of benign prostatic hyperplasia (BPH).

METHODSWe randomly assigned 60 BPH patients to a control and a combination group of equal number, the former aged 62.03 ± 10.19 years with a disease course of 3.24 ± 2.18 years and the latter aged 64.77 ± 10.33 years with a disease course of 4.09 ± 2.63 years. We treated the patients in the control group with Tamsulosin at 0.2 mg qd and those in the combination group with Tamsulosin at 0.2 mg qd plus Xipayimaizipizi at 0.5 g tid, respectively, both for 4 weeks. Then, we obtained the mean frequency of nocturnal urination, maximal urinary flow rate (Qmax), residual urine volume, International Prostate Symptom Score (IPSS) , and quality of life scores (QOL) of the patients, and recorded their adverse reactions.

RESULTSBefore treatment, the nocturnal urination frequency, Qmax, IPSS, and QOL were 3.60 ± 1.81, (10.40 ± 3.53) ml/min, 22.47 ± 8.58, and 4.43 ± 1.50 in the control group, as compared with 3.43 ± 1.61, (10.14 ± 3.43) ml/min, 21.93 ± 8.79, and 4.73 ± 1.31 in the combination group. After 4 weeks of medication, the combination group showed more significant improvement than the control in the nocturnal urination frequency (1.30 ± 1.18 vs 2.27 ± 1.60), Qmax ([13.85 ± 3.15] vs [14.36 ± 3.03] ml/min), IPSS (13.00 ± 1.53 vs 17.20 ± 8.43), and QOL (2.57 ± 1.61 vs 2.93 ± 1.68), all significantly better than the baseline (P < 0.05). The combination therapy achieved remarkable improvement as compared with the control in the nocturnal urination frequency (- [2.13 ± 1.11] vs -[1.73 ± 1.07]), IPSS (- [8.93 ?6.01] vs -[4.80 ± 3.87]), and QOL (- [2.17 ± 1.12] vs -[1.50 ± 1.01]) (P < 0.05), but exhibited no significant differences from the latter in Qmax ([3.72 ± 2.281 vs [3.95 ± 2.53] ml/min) and residual urine volume (- [34.30 ± 37.43] vs - [26.43 ± 30.49] ml) (P > 0.05). Adverse reactions were found in 5 cases in the combination group (16.67%) and 3 cases in the control (10%) , with no remarkable differences between the two groups (P > 0.05).

CONCLUSIONThe combination therapy of Xipayimaizipizi Capsules and Tamsulosin can improve the symptoms of BPH and the patients quality of life of.

Objective • To investigate the effects of chaperone-mediated autophagy (CMA) on α-synuclein oligomers level in the Parkinson's disease (PD) cell model with impaired ubiquitin proteasome system (UPS). Methods • The PD cell model was established by adding the proteasome inhibitor lactacystin in the SK-N-SH cell line stably transfected with wild type α-synuclein. The levels of α-synuclein oligomers, lysosome-associated membrane protein type 2A (LAMP2A) and 70 kDa heat shock homologous protein (HSC70) were detected using Western blotting. CMA function was inhibited with LAMP2A siRNA, and its effects on α-synuclein oligomers and cell viability were detected. Furthermore, the interaction of LAMP2A with α-synuclein oligomers was detected by immunoprecipitation. Results • In the PD cell model, the levels of α-synuclein oligomers, and CMA related proteins, i.e. LAMP2A and HSC70, were increased. Inhibiting the expression of LAMP2A further increased α-synuclein oligomers level, while it decreased cell viability. Furthermore, LAMP2A could interact with α-synuclein oligomers. Conclusion • In the PD cell model, CMA is one of the pathways regulating α-synuclein oligomers level. Inhibiting CMA function can further increase the α-synuclein oligomers level and deteriorate cell survival.

Parkinson's disease (PD) is an incurable neurodegenerative disease, which seriously affects the life quality of patients. Researches in recent years found that excessive production or abnormal structure of α-synuclein and forming toxic aggregates are the key factors in the pathogenesis of PD. In a variety of mechanisms, abnormal modification of α-synuclein is closely related to its aggregation state, such as phosphorylation, ubiquitination and nitration modification, but the exact effects are still uncertain. Recent studies have shown that acetylation modification of α-synuclein plays an important role in the abnormal aggregation of α-synuclein. This article reviewed the progress of acetylation modification of α-synuclein.
